When You Should Not Wear Sister Sizes?
Are there any occasions where you should not use sister sizes? If you’ve got a bit more up top and you need your sports bras to help keep things up. I would not recommend wearing the ‘big sister’ size, the ‘up a band size’ sister size.
Support comes from the band and there is a risk the band will be too loose and not provide the support you need. To ensure you get the support you need it is more common to go down a sister size rather than up.
The Advantage of Sister Sizes
So, you’ve spent a long time researching and searching for the perfect bra for you. It ticks all your boxes, it’s high impact, racerback, wirefree and looks perfect but it is not available in your size. Don’t despair as it is perfectly OK to check if a sister size is available. Go up one cup size and down one band size. Or down a cup size and up a band size. Try it for yourself, it almost always works!
Common Questions?
Both my band and cup don’t feel right, what do I do?
If the band and cup feel slightly loose, try going down a band size whilst keeping the cup size the same; 12D to 10D. If the band fits well but the cup still isn’t quite right, try going up or down by one cup size; try a 10C or 10DD.
If the band and cup feel slightly tight, try going up a band size whilst keeping the cup size the same; 12D to 14D. If the band fits well but the cup still isn’t quite right, try going up or down by one cup size; try a 14C or 14DD.
How do I know to go up or down a sister size?
Which sister size you select depends on how your band feels and where you fasten it. Your band should fit you comfortably on its loosest hook and eye setting.
If you’re on the tightest fastening and it still feels loose, try going down a sister size. If you’re on the loosest fastening and it feels too tight, try going up a sister size.
My sister size still doesn’t fit should I go up or down another size?
I recommend only going up or down one sister size. If the sister size still isn’t the right fit, I recommend doing a remeasure and visiting our fitting room to double check if you started with your right size. If you want further advice, please contact me I am happy to help you.
